Be it knownthat I, BIOHARD Bnoom' WAY; a citizen ofthe United Stetes residlng: inMoo'dus, in the countyotMlddlesex and a State of Connecticut, have invented new and Improved Twisters, of, which n the following isaspecifications i l invention relates; to the class of 'devices employed for twlsting a number of threads or strands to form a singlefthread or strand voi alargersizefas iscornn only practiced inthe arto'f Cordage, and in sp1nn1ng, it weaving andthe like, and an object'ot ny I "invention,-an1'ong others, is the'productlon of a twiste'rfframe or spindle thatmaybe rotated at a high rate of speed, onethat will effectively accomplish the work requiredof it, and one that shall oceupya minimum amount of space. 1 l e v F0119 form of twisting frame onspindle' embodying my invention and in the k construction and useof which the objects here in set out, i as well 1 as others; may be attained, is illustrated in the accompanymg Figure l'is a view in broken away to show construction;

F igure '4: 1s vlew of a portlon of a frame qillustratingla different manner of; mounting the fileljsfl HIn the accompanying drawings the numeral6 "indicates my improved twisting frame that is substantially rectangular in form when viewed in; side elevatlon and comprises sides 7, abottom bar 8 atopbar 9;and cross bars 10',-allvof wljlilcn areprett erably composed of netal forniedin a single piece. Tw ster h projects upwardly from "the bottom of 1 and withln each] flier frame and skewers of latch bars 19, each pivotailly attachedrat one endto a sidebar of the flier andhaving te se frames, or spindles as they are frequently called, have, prior to Qmyf invention, embodied a structurein which" i [the bobbins or spools have been so arranged upon a rotating frame as to, be revolved about theaxis of said frame. Myimproved twister-head orframecomprises a structure "in which the bobbinsorspools are arranged withtheir axes coincident 'with the axis of rotationzof the frame composed of the sides top, bottomand cross bars above mentioned,

said'cross bars 10 beingarranged at regular lntervalsalongrthe frame, as herein shown this jframebeing arranged to receive three bobbins and thereforehaving two of said cross bars. Fhersll are rotatably mounted on the bottom and cross bars, each flier comprising n rectangularly shaped frame withgaflier-pinion 12 rigidly securedlto its under surface andwa bearing stud 13' projecting downwardlyironi the piniontinto a bearing recess in the bjarthat supports the fi1er,-in the construction herein shown this recess being fin a in driven into'the cross orbottom bar: maid pinions nlay be secured tothe'fliers in any suitable manner alncl 'the studs andtheir bearings inthe crossbars orbottom bar may be of any desiredconstruction to enable the flier to rotate freely 011 its support. A skewer stud 16 are pivotally secured to said studs so l that they may be placed inan inclined posielevation of a twlster frame embodying myinvention with parts tion to receive the bobbins 17 that are loosely mounted on the skewers to rotateindepend cntly thereof. A loop or guide 18 is formed on thegoutside ofeach flier to receivethe thread from the bobbin thefeonJ The bobbins are retained in placebymeans at itscenterasocket to receive the upper end of the skewer, the end of each latch lba'r' opposite itsf pivot resting upon a lip projecting from the side ofthe flierirom which lip a pinprojects through the latch and a spring presses the latchbar against the lipin a manner common to devices of this kind. hollow shaft 20 on the upper end of each flier projects into aholt: comprising a bearing in a flier SupportingbarQl extending across the twisting frame and secured as by means or screw boltsto sup ports 22. i s jFlier rotating shafts 23 are supported in a vertical position by the bottom and cross bars of the frame 6,: these shafts being stepped in bearings 24 secured to the under side "of the bottom bar '8, said shafts ex tending throughrecesses formed in the edges b 1 of thefcross bars and being supported by '60 and from th'ence through a hole in the top bar or a cross bar next above it, the threads brackets projecting from the sides 7 under neath the cross bars and as shown in Flg- 'ures 1 and 3 of the drawings. These shafts have flier driving gears 25 secured thereto and in mesh with the pinions 12. In order that all of said driving gears may properly mesh with their respective pinions, and without binding action therebetween, the gears 25' are frictionally secured to their shafts so that under the application of a certain amount of power the shafts may rotate independently of the gears, the frictional connection however being sufficient ted-rive the fliers under ordinary conditions of use. The connectlon herein shown for each gear comprises a spring 26 pressing against agear and retained in place as by means of a'collar 27 secured to the shaft in any-desired manner.

1 The frame 6 is mounted to rotate preferably with its axis vertically disposed and a numberof these twister frames may be supported} on a rail 28, in a manner that will belreadily understood by those skilled in the art In mounting myimproved-frame I employ a flanged step 29 that may be se-' curedto the rail in any suitable way, this step-having a short stub shaft 30 projecting from thebottom of and rigidly secured to the bottom bar 8 of the frame, in the structure herein shown this shaftcomprising a stud driveninto a hub 31 on the bottom of i the frame and having the recess 14in its upper end to receive the bearing stud from the pinion of the lowermost flier in the frame, and in a manner as hereinbefore described with respect to the other fliers.

f A twisting frame driving pulley 32 is secured to a twister frame supporting shaft 331projecting from the upper end of the twister frame into a bearing in a bracket 34 supported in any suitable manner com- -mon to twisting frame apparatus.

vThe shafts 23 are rotated by means of pinions '38 on the lower ends thereof meshingwith'a driving gear 35 secured to a sleeve 36 rotatably mounted on the step 29 and having a flier driving pulley 37 secured thereto, each of the pulleys 32 and 37 being designed to receive beltsfor driving them.

. bins or spools under a loop or guide 18 and through an opening 39 in a hollow shaft 20 fromthe several bobbins being passed through holes diagonally arranged in said bars, and each of the threads passing through an opening in the web of the pulley 32, and from thence into an eye l0 in the side of the supporting shaft 33, and out at the end of said shaft from which point it will pass around a tension roller and from said roller to a reel in a manner that will be readily understood, and for this reason said roller and reel are not shown in the drawings herein.

Ina slightly different arrangement of the device illustrated in Figure 4 the twister frame will be constructed as above described and the flier rotating shafts will be mounted and driven as hereinbefore set forth. The fliers 41, however, will be mounted so that the axes of the bobbins will extend transversely to the axis of rotation of the fliers. In this construction the support for the 1101- low shaft 42 for the upper part of the flier, willaproject from what was a side part in theconstruction hereinbefore described, and the flier pinion 43 will be secured to the other side part. In this arrangement the support ist on the flier frame will have a recess for the free end of the skewer for the bobbin, andaspring pressed pin with knob 45 on its end will enter the recess in a manner to hold the free end of the skewer in place in said recess.

I claim 1. A rotatably mounted twister frame, a plurality of bobbins mounted for twisting rotation on said frame, shafts rotatably mounted on said frame on opposite sides thereof, means comprising a frictional driving connection between saidshafts and'each of said bobbins, and means for driving said shafts.

2. A rotatably mounted twister frame, a plurality of bobbins mounted for twisting rotation on said frame, shafts on opposite sides of said bobbins, a plurality of members each frictionally secured to each shaft and in driving connection with said bobbins, and means for driving said shafts.

3. A rotatably mounted twister frame, a bobbin mounted for twisting rotative movement on said frame, said axis of rotation. of said bobbin being in line with the axis of rotation of said frame, a shaft rotatably mounted in said frame on each side of said bobbin, toothed driving members rotatably mounted on said shafts and frictionally connected therewith, and a toothed connection between said members and said bobbins.

At. A twister frame rotatably mounted with its axis vertical, a bobbin mounted for twisting rotation on said frame and with its axis in line with the axis of said frame whereby the bobbin rests upon its end on said frame to provide frictional resistance to its rotation, means for rotating said bobbin, and means independent of the pull of the thread for rotating said frame;
